Energy costs continue to take up a significant portion IT budgets, and it seems that there is no end
in sight. According to Gartner, “The underlying consumption of energy in large data centers to power
and cool hardware infrastructure is likely to increase steadily during the next 10 years. This scenario
is likely because of the increase in energy consumption of processors, servers, storage devices, and
network-type appliances.” Many companies are already seeing their energy costs escalate. The following
example conveys the magnitude of the problem:
A facilities executive of a global investment bank strode into the office of the CIO. He dropped an
electricity bill on the CIO’s desk and said, “I believe this is yours.” The bill, which was the first the
CIO had ever been asked to pay, was for nearly $2 million. The facilities executive added that his
department is no longer able to sustain this level of charge, noting that the IT energy cost per square
foot is about 17 times that of other departments.
Much of the power that IT consumes is being wasted. Industry experts have reported that the cost
of wasted server capacity is more than $100 billion per year. Cost is not the only problem. Energy
consumption has become a severe constraint on growth. In London, for example, there is now
a moratorium on building new data centers because the city does not have the electrical capacity
to support them.
Many IT organizations view Green IT as a major undertaking that involves replacing current equipment
with new “green” equipment that has low energy consumption. Most of these organizations, however, do
not have the capital budget to finance such broad and sweeping changes. Fortunately, there is a more
practical way to achieve Green IT objectives. Rather than looking at greening IT as one formidable task,
think of greening IT as an incremental and continuing process that you can tackle in bite-sized pieces.
You can begin with a step that requires minimal capital investment and still delivers a huge payback
in energy conservation. You can use what you have in your infrastructure without having to buy new
hardware. This paper presents that step as part of a holistic approach that addresses Green IT within
the broader context of increasing business service efficiency. This strategy is based on Business
Service Management (BSM), a comprehensive approach and unified platform for running IT, which
offers an effective and proven way to manage IT based on business priorities. Business service efficiency
strives to achieve a balanced set of outcomes that include financial gains and operational yields,
in addition to environmental benefits.
This paper addresses, in a unified and systemic way, many of the issues — including Green IT — that
IT has been grappling with in piecemeal fashion. Through this holistic approach, you can address the
issues in context rather than in isolation. As a result, you’ll realize greater improvement in service and
greater reduction in operations costs and capital expenses — and you’ll achieve Green IT in the process.
